Small Cannon

[slapdick]

It may be safer to use as a post driver. It could end up as a pipe bomb. Before shooting this you might check out the minimum standards set for construction of bp cannon. BP cannons and mortars are great to shoot but be safe. Hereis a link to standards. https://www.go2gbo.com/threads/safe-loads-construction-new-cannon-builders-design-standards.69739/

It would 100% be safer to use as a post driver.

I used E-70s to weld it which is good for 70,000 PSI tensile strength, the tube itself has 95000 psi tensile strength, and with a 4 oz of powder + the size of the bore, shouldn't ever reach higher than 6000 psi with this.

I'll see if I can upload the video of it being test fired.

Many yrs ago when I was at La Tech the engineering dept made a half size civil war cannon to fire at football games when we scored a TD. It blew up (split open) on the 2nd shot.
